Hello Dan, a 3 level ACDF is a major surgery,(I am fused from C4-C7) and yes you can expect pain everywhere, but I believe if you take your medications according to your Dr there should be no addictions issues, The drugs are prescribe to help with the pain issue so that you are not suffering. If your family Dr or surgeon prescribe you a pain pill then take as ordered or take half the amount untill your pain level is tolerable take care, Bunz
